TEXAS_HOLDEM, NO_LIMIT, T4-56395985-72
played at "New Haven" for USDTC from 2007-12-19 23:05 until 2007-12-19 23:05
Seat 1: Dr Zen ($4,915 in chips)
Seat 3: RoyzeNoBoyz ($6,795 in chips)
Seat 5: Lec12345 ($3,290 in chips)
ANTES/BLINDS
Dr Zen posts blind ($100), RoyzeNoBoyz posts blind ($200).

PRE-FLOP
Lec12345 folds, Dr Zen bets $500

Standard with a king.

RoyzeNoBoyz calls $400.

FLOP [board cards:4HTDKC ]
Dr Zen bets $900, RoyzeNoBoyz calls $900.

I have to assume I have the best hand. Three possible cases after he calls:

1/ He has a king.
2/ He hit something else.
3/ He has a draw.

In case 1, I am probably doomed to loose more chips because I'm very unlikely to fold top pair.
In case 2, if I check, he might think I was cbetting and then I can win his bet. If I just lead out again, he probably folds.
In case 3, he might semibluff. I am taking a risk if I check, but this guy has played quite aggressively.

TURN [board cards:4HTDKC5H ]
Dr Zen checks, RoyzeNoBoyz bets $5,295 and is all-in, Dr Zen calls $3,415 and is all-in.


He shows JT.

Well, that's great right? I'm miles ahead and he only has five outs.

Surely this time it will...
RIVER [board cards:4HTDKC5HJC ]

Oh no. Silly me.
