This guy doubled up second hand when he flopped a boat w/ JJ and busted a flush. That has been the only hand he's played.

Preflop I figure him basically for AQ+ TT+. TT and AQ seem most unlikely of the bunch.

I checked the flop because every hand I put villain on hit the flop in some way and he certainly was going to make some bet. The problem with a lead is that any hand he could have will probably raise this flop so I get no info. I thought it best to c/c and if he checks behind on the turn to get value on the river. However his turn bet looked real strong so I checked river too.

Being 2 of the big stacks at the table I didn't want to tangle without a really big hand. Looking back I should have maybe blocked the river, but the pot was already large so I just checked intending to fold to a push.

Too slow?
