Wow Piers- Interesting hand!
I think id have raised the flop and led here, but thats just me.
Well, i dunno there are alot of ways to look at this hand like there are alot of ways to look at everyhand, and of course hindsight is 20/20....The Check on the turn seems to indicate that he's weak, and your check behind indicates that you are weak too. When the 10 paired and he bet, it means either one of few things- either
(a) He has some sort of a hand that he thinks will win a showdown (unlikely- he'd have bet the turn with any hand to make the spade draw pay)
(b) He knows he cannot win except by betting, so hes takin a stab
(c) he is an idiot, and bets with missed Ace- high hands that almost ALWAYS, if called, are no good, and if they are good, get folded to (people do this all the time)
(d) He might actually be value betting his ace high (some players that claim to be really 'good' say they do this sometimes)
The problem here is just that (c) IMHO, is just too likely- unless he has been raising you up alot from the SB. Idiots do that all the damn time...And at a 3/6 game, i wouldnt exactly put players on a sophisticated play like an ace high value bet...So it seems a contest beteween (c) and (b) with a remote possibility of (a). With a pot that small, i would think (b) is not all that likely...
All in all, i dont mind your call too much with the second nut no pair...its probably a sideways EV move? Its just that the pot is so small, and the ace is so likely that i probably wouldnt have called, unless the guy is LAGgy enough that the only way he'd check the turn to you means that his hand is so bad that he cant even fire one more off at you. As it were, he actually improved on the turn (more or less).
This is another thing i worry about when a LAGgy Blind thief checks it to me - LAGs will often fire with nothin, then when they actually pickup something, they'll go into check/call mode, then bet it when they tihnk its good. How many times have you seen a bluffer jamming a draw and make a shitty pair on turn or river, and check/call it down, when you KNOW he'd have bet if he missed?
So, all this crap taken into consideration, i would probably just say, fuck it the pots too small, and let him have it on the river. But like i said, id have raised the flop and led the turn, and probably either picked up the pot that way, or else won with Qhi if he decided to make the godawful straight chase onna flushie board in a HU pot.
But damn. It feels nice to own someone with a queen high, dont it?
