Ive recently had a rethink on how i approached my bluffs.
Previously a bluff for me would be about winning a hand when i missed the board. Now, with a little deeper thought, i plan a bluff before the flop & plan to win a big pot (rather than just the hand). This means planning a double-barrell early - hoping for a call to build the pot with barrell 1, and taking it down with barrell 2.
I've had some success with this. A couple of factors when to do it; almost always in late position and ideally against rather standard tight agressive players, who are ripe for double barrelling.
Once i sense a players range as being something like broadway hands & any pockets, I'll target this player for a double barrell.
Deep stacked in a cash game my opponents bet size on the flop doesn't give too much info as the pot is fairly small at this point. If he overbets it 2:1 alarm bells might ring, but anything from 50%-80% is standard and ideal for raising.
My raise here is barrell 1 & usually around 2.5x their bet. Now previously I'd always hope to get a fold with any bluff - but now i almost always hope for a flat call. If my opponent comes back over the top & i have air, i usually let it go here. A fold from my opponent is fine, but ideally i like a flat call for a bigger pot.
When the turn card comes, I'll almost certainly fire barrell 2 if my opponent checks and this betting sequence has served me well recently. The pot is also decently sized as my opponent has called a raise post-flop.
If my opponent bets, firing a 2nd barrell really depends on numerous factors, mainly the turn card & his bet size. If the turn card is a brick and his bet size is a small-ball, I'm pretty sure I'm going to fire my 2nd & last bullet here. If i don't get a fold then by this point it seems likely my opponent believes he has the strongest hand and is going nowhere.
A draw-heavy card on the turn & a larger bet (70%+ to pot) poses a much trickier decision, at this point information is king. Such as, would my opponent call a raise on the flop with a draw, is he prone to
bluffing, or does he try to protect hands such as top pair? Sometimes in such a situation i read my opponent as having made top pair Q or something on the flop & get them off it with my 2nd barrell bluff. Often though i can either misread and run into a big hand... or get called down by an opponent who loves that top pair too much.
With my double barrells on the turn, I'm finding a high variance, feels great when it comes off and a disaster when my 75o runs into a set. Maybe i should track it more to see if it's profitable & if I'm choosing the right spots & players to try it with, but its a fun play to make for sure.
