In a 4-bet pot with top pair and a shallow SPR, we must commit our stack for value rather than slowing down on safe runouts.
Flop Analysis
On this Q-high texture, we have a massive range advantage. Betting half-pot with top pair top kicker is a strong value play that targets JJ-99 and spade draws.
**Ranges:** Our 4-betting range is dense with AA, KK, and AQ, while the BB's calling range is capped, often containing hands like JJ, TT, or AQs/AK that didn't 5-bet shove.
**Sizing:** A roughly 50% pot sizing (28.3BB into 59.8BB) is effective here; it sets up a comfortable shove on most turns given the shallow SPR.
**Position:** Being in position allows us to dictate the pace of the hand and realize our equity effectively against the BB's checking range.

> **Takeaway:** In 4-bet pots on favorable boards, use medium sizing to extract value from capped ranges while setting up a turn commitment.
Turn Analysis
The turn is a total blank. With an SPR of 0.36, there is no room for maneuvering; we must shove to get called by worse Queens or desperate draws.
**Math:** With only 41.5BB left into a 116BB pot, we are mathematically committed. We only need Villain to call with a worse hand a small fraction of the time for this to be the highest EV play.
**Board:** The 2d doesn't change the board state. We still beat all of Villain's likely calling range except for rare sets like 88 or 55 that might have flatted the 4-bet.
**Plan:** By shoving now, we maximize value from hands like KQ, QJ, or AsKx/AsJx that might find a fold if a third spade peels on the river.

> **Takeaway:** When the SPR is below 1.0 on the turn with top pair, prioritize getting the rest of the money in on safe cards.
