It's not just the lack of a time bank on BOL and Full Flush that I have a problem with. It's the incredibly short play clock. I'm the type of player that very rarely goes into my time bank, on the sites that have them. The time in the standard play clock is usually more than ample time to make any decision.
On BOL and Full Flush, however, the allotted on the regular play clock has proven on more than one occasion to be too short to calculate optimum bet sizing. I have literally flopped aces full and timed out and had my hand folded before I could calculate my bet size and type it in. We're talking about having no question as to whether or not I'm going to play the hand. I just flopped aces full. There is no question that I'm going to play it. I already know that, with three other players in the pot, I'm going to fire out 2/3 of the pot. I just need calculate that amount. After doing some quick math in my head, I type the resulting number into the box and hit enter, with what looks like a few seconds to spare, only to see those last few seconds tick away and my hand be folded.
