Earlier today while playing for $5 heads up:
The first match I lost a hand where I had 10-9 offsuit and the flop came 6-7-8 with two spades. I bet, the other player called.
The turn came another spade, I pushed all-in, he called showed 2-5 (5 is spade).
The river came another spade so he won with a flush on the river with a 2 in his hand.
THe next game i had 6-6 preflop, raised and he called.
Flop is 4-5-7 rainbow. I bet he calls.
Turn is another 7, I check, he bets tiny, I call.
River is a 7, I put him all-in, he calls and flips over 7-8.
